概括
骨髓细胞核分化抗原 (MNDA) 表达在形血细胞状树突细胞瘤 (BPDCN) 中因解剖部位和时间而异. MNDA更频繁地表达为非皮肤BPDCN,警告不要使用它来排除BPDCN.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫组织化学 免疫组织化学
背景情况:
- 囊性血细胞状树突细胞瘤 (BPDCN) 是一种罕见的,激烈的血液瘤.
- 在形态和免疫表型上,BPDCN可以模仿急性髓性白血病 (AML).
- 以前认为骨髓细胞核分化抗原 (MNDA) 在BPDCN中不存在,有助于AML分化.
研究的目的:
- 在BPDCN中重新评估MNDA表达.
- 调查MNDA作为BPDCN和AML的诊断标志物的可靠性.
主要方法:
- 10年来,从斯坦福大学档案中回顾分析了8起BPDCN病例.
- 在骨髓,乳腺和皮肤样本上进行的MNDA免疫组织化学.
- 在某些特定情况下,通过下一代测序进行分子分析.
主要成果:

Differentiation of Common Myeloid Progenitor Cells
3.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

B Cell Activation and Differentiation
1.6K
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
